# Babylon.js Website

> Babylon.js: Powerful, Beautiful, Simple, Open - Web-Based 3D At Its Best

## Project Overview

This is the official website for Babylon.js, one of the world's leading WebGL-based graphics engines. Babylon.js is a fully-featured, open-source 3D rendering engine built on JavaScript and web standards that brings powerful, beautiful, simple, and open 3D experiences to everyone on the web.

## What is Babylon.js?

Babylon.js is a comprehensive 3D framework that:
- Runs on WebGL 1.0, WebGL 2.0, and WebGPU platforms
- Provides a complete scene graph with lights, cameras, materials, meshes, sprites, layers, animations, audio clips, GUI elements, and actions
- Offers scene interaction through ray casting, behaviors, and mesh picking
- Supports physics engines including Cannon.js, Oimo.js, and Ammo.js
- Features best-in-class physically-based rendering (PBR)
- Includes a powerful node material editor and visual scene inspector
- Supports multiple file formats including .babylon, glTF, STL, OBJ, and more
- Provides cross-platform compatibility eliminating platform complexity
